Cosmetics

Did a few cosmetic changes, more to come. Actually did a bunch more earlier and then accidentally wiped the files. So will have to go back today and re-do. 

Have in mind a feature I saw on Piggycoin where there was an IRC client built-in. That'd be fun. Also a GUI which lets the user keep track of the mining the way minerd does when mining with it.

Anyway, you can look at the screenshots, see that it's working well under a *buntu 64-bit. 

Going to do a bunch more work soon. Even if you don't use, just for myself.
